The Australian 50 cent denomination was first introduced as a silver coin with decimalisation on 14 February 1966, but was changed in 1969 to its current specifications: a large dodecagonal (12-sided) copper-nickel coin; apart from the usual design featuring the Australian Coat of Arms, the denomination is also extensively used to issue circulating commemorative coins with various reverses. It is one of the heaviest coins in regular circulation in the world.
Apart from circulating coins, the Royal Australian Mint has a range of Non-Circulating Legal Tender (NCLT) 50 cent coins issued for collectors, such as this one.
This coin was issued for the festive season and is part of a Royal Australian Mint series of coins meant as a Christmas Decoration.
The mint says about it:
The stunning NSW Christmas bush Ceratopetalum gummiferum, with its distinctive white flowers and red fruit appearing together in glorious festive sprays, is a perfect celebration of summer Christmas in Australia.
The Royal Australian Mint celebrates the upcoming festive season with this 2023 50c Coloured Uncirculated Coin inspired by our native flora. The beautiful and distinctive red fruit of the NSW Christmas bush is gloriously reimagined as a five pointed Christmas star. While the gorgeous coin design is further enhanced by the hanging decoration card available in five translucent summer colours, gilded with silver foil accents.
The Mint’s 2023 Festive Floral Christmas decoration coin is the perfect Kris Kringle gift for one and all this Christmas. |
